05). The T6SS-positive isolates formed significantly more biofilm mass than the T6SS-negative isolates (mean?±?standard deviation [SD], 0.3?±?0.09 vs.0.16?±?0.06; P?&lt;?0.01). Compared to the T6SS-negative isolates, the T6SS-positive isolates had a higher frequency of virulence genes (rmpA, fimH, entB, kfu, ybtS) and the pLVPK-like plasmid (P?&lt;?0.05).
In conclusion, the prevalence of the type VI secretion system is high in clinical Klebsiella pneumoniae isolates in a Chinese teaching hospital. T6SS-positive strains show higher biofilm-forming activity with high drug resistance and exhibit higher virulence potential.

Meta-analysis revealed liraglutide reduced hemoglobin A1c (HbA1c) (WMD = -0.67; 95% CI[-0.94 to -0.39]; P less then 0.00001), fasting plasma glucose (FPG) (WMD = -0.80; 95% CI[-1.06 to -0.54]; P less then 0.00001) and 2 h plasma glucose (2hPG) (WMD = -1.64; 95% CI[-2.12 to -1.16]; P＜0.00001); improved left ventricular ejection fraction(LVEF) (WMD = 4.79; 95% CI[4.08-5.51]; P less then 0.00001), left ventricular end-diastolic diameter (LVEDD) (WMD = -5.70; 95% CI[-6.67 to -4.72]; P＜0.00001), E/A (WMD = 0.13; 95% CI[0.11-0.14]; P less then 0.00001) and left ventricular posterior wall thickness (LVPWT) (WMD = -1.86; 95% CI[-2.16 to -1.55]; P less then 0.00001); reduced total cholesterol (TC) (WMD = -0.48; 95% CI[-0.56 to -0.39]; P less then 0.00001), triglycerides (TG) (WMD = -0.42; 95% CI[-0.59 to -0.26]; P less then 0.00001), low-density lipoprotein cholesterol (LDL-C) (WMD = -0.41; 95% CI[-0.55 to -0.26]; P less then 0.00001), and increased high-density lipoprotein cholesterol (HDL-C) (WMD = -0.19; 95% CI[0.13-0.24]; P = 0.0005). As for safety assessment, liraglutide did not increase the incidence of hypoglycemia (OR = 0.75, 95% CI[0.32-1.77], P = 0.51) and gastrointestinal (OR = 1.15, 95% CI[0.72-1.85], P = 0.55) events. Consequently, liraglutide had favorable effects on blood glucose, cardiac function, lipid profile and an acceptable safety profile.Serum insulin-like growth factor-1 concentration (sIGF-1c) is reduced in various hepatopathies in humans and dogs. This work aimed to evaluate sIGF-1c in dogs before and after congenital extrahepatic portosystemic shunt (cEHPSS) attenuation, in relation to surgical outcome (closed vs. persistent shunting). Secondarily, it aimed to assess if sIGF-1c can discriminate between cEHPSS and portal vein hypoplasia (PVH) and finally compare sIGF-1c ratio (postoperative/preoperative sIGF-1c) to pre-prandial serum bile acids (preBA), post-prandial bile acids (postBA), bile acid stimulation test (BAST) and fasting ammonia (FA), regarding surgical outcome. Thirty-nine dogs were included 15 with closed cEHPSS, 15 with persistent shunting and nine with PVH. Transplenic portal scintigraphy was used to classifiy surgical outcome. There was no significant difference in sIGF-1c between dogs with cEHPSS and those with PVH (P &gt; 0.05). Postoperative sIGF-1c increased in all dogs (P less then 0.001 and P = 0.023 for closed and persistent shunting, respectively) and the increase was more pronounced in closed cEHPSS than in persistent shunting (P = 0.006). Using an optimal sIGF-1c ratio cut-off of 2.23, the sensitivity was 93.3% and the specificity was 66.7% for differentiation between surgical outcomes. Serum pre-prandial bile acids, postBA BAST and FA had sensitivities of 80%, 86.7%, 86.7%, 60%; and specificities of 100%, 93.3%, 93.3%, 100%, respectively. There was a greater increase in sIGF-1c after shunt closure than during persistent shunting; nevertheless sIGF-1c ratio was inferior to advanced imaging to assess surgical outcome.There is mounting evidence that kidney ischaemia/hypoxia plays an important role in feline chronic kidney disease (CKD) development and progression, as well as in human disease and laboratory animal models. Ischaemic acute kidney injury is widely accepted as a cause of CKD in people and data from laboratory species has identified some of the pathways underlying this continuum. Experimental kidney ischaemia in cats results in morphological changes, namely chronic tubulointerstitial inflammation, tubulointerstitial fibrosis, and tubular atrophy, akin to those observed in naturally-occurring CKD. Multiple situations are envisaged that could result in acute or chronic episodes of kidney hypoxia in cats, while risk factors identified in epidemiological studies provide further support that kidney hypoxia contributes to spontaneously occurring feline CKD. This review evaluates the evidence for the role of kidney ischaemia/hypoxia in feline CKD and the proposed mechanisms and consequences of kidney hypoxia. As no effective treatments exist that substantially slow or prevent feline CKD progression, there is a need for novel therapeutic strategies. Targeting kidney hypoxia is one such promising approach, with therapies including those that attenuate the hypoxia-inducible factor (HIF) pathway already being utilised in human CKD.The aim of this study was to serially evaluate the serum concentrations of total thyroxine (tT4), free thyroxine (fT4) and thyroid-stimulating hormone (TSH) in dogs with canine parvoviral enteritis (CPVE) during a 5-day hospitalisation period and assess the association of these hormone concentrations with the outcome and the development of systemic inflammatory response syndrome (SIRS). Dogs with confirmed CPVE that were hospitalised for at least 5 days were included. The thyroid hormones concentrations were measured on days 1, 3 and 5 of hospitalisation. Twenty-eight dogs were included. All (28/28, 100%), 19/28 (69.7%) and 23/28 (82.1%) dogs had a low serum tT4, fT4 and TSH concentration, respectively, on at least 1 day during the hospitalisation period. Overall, 11/28 (39.3%) dogs were diagnosed with SIRS on at least 1 day. In survivors, serum tT4 concentration was significantly higher on day 5 (median, range 11.8?nmol/L, less then 6.4-32.2?nmol/L) compared to those on days 1 ( less then 6.4?nmol/L, less then 6.
